----------


某天 + n天：

strtotime可以接受第二个参数，类型timestamp,为指定日期

echo date('Y-m-d', strtotime ("+1 day", strtotime('2011-11-01'))), "

";

echo "今天:",date('Y-m-d H:i:s'),"
";

echo "明天:",date('Y-m-d H:i:s',strtotime('+1 day'));

?>

上一行输出当前时间，下一行输出明天时间

这里+1 day

可以修改参数1为任何想需要的数  day也可以改成year(年)，month(月)，hour(小时)，minute(分)，second(秒)

如

date('Y-m-d H:i:s',strtotime("+1 day +1 hour +1 minute");
